My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
How I see it, not needing to be in the big social is a privilege. If you can stay out, enjoy. I know a lot of artists etc. who, if they left the big social, would soon have no work or income.
Me? I open LinkedIn when I need a new job, that's all.
